SPECIFICATION forming part of Letters Patent No.339,680, dated April 13, 1886.

A pplication filed September 1l, 1885. Serial No. 176,791. (No model.)

To all whom, it may concern:

Be it known that I, JOHN E. NATHAN, a citizen of the United States, residing at New York, in the State of New York, have invented certain new and useful Improvements in Snow-Flows7 of which the following is a speciication.

The object of my invention is to construct a plow for removing snow from railroad-tracks; and my invention consists in the features and details of construction hereinafter described and claimed.

In the drawings, Figure l represents a side elevation of my improved snowplow. Fig. 2 represents a plan view of the same, and Fig. 3 represents a front elevation.

A represents the top one of my series of snowplows; B, the one next below; C, the one next below it; D, the bottom one of the series, and E the car to which the snow-plows are attached.

In making n snow-plow of my construction so that it will be deposited at either side of l ters Patent isthe track. The general form and outline of these plows forming the series need not differ l materially from the general form and contiguration ot' snow-plows as ordinarily construct' ed; but the snow-plow is made in a series of plows, each one advanced beyond the other from the lowest to the highest, so that as the car is propelled or advanced into the snowdrift the upper plow will remove the top portion or section of the drift, thus diminishing its height before the next plow has entered the drift. In this way the height of the drift will be diminished as each plow successively reaches it, so that by the time the last one of the plows has reached the drift there will remain but a small depth oi' snow to be removed. In this respect my snow-plow differs from any Ihave ever seen or of which I have ever heard. There the snow-plow enters the drift, as is ordinarily the case, at the bottom without having removed any ofthe snow from the top, v

so that the whole depth of the drift is required to be removed at once, the plow necessarily packs and presses the snow together', so that it becomes impossible to propel the car or engine to which the plow is attached forward and raise and remove the snow; but by removing a portion of the drift at a time, beginning at the top, no diliculty of this nature is to be encountered. v A

I am aware that snow-plows have been made with inclined ways arranged one behind and below the other from front to rear, provided with internal chutes for conveying the snow to the top ot' the plow to be thrown off by V- shaped wings. I also acknowledge the existence of snow-plows provided with chutes arranged one above the other, and projecting forward one beyond the other to the top, provided with wings or conveyers for the snow on the outside, arranged to discharge the snow from the side on or near the line at which it was taken onv the plow. These features I wish to disclaim.

What I desire to claim and secure by Let- A ,railway snowvplow consisting of two or more plows arranged one above the other in a con tinually-advancing series from the lowest plow, the lowest plow being the farthest back, and each succeeding plow being advanced beyoud the one immediately below it, and each plow being provided with a continuous external channel extending to the top of the elevation of the snow, whereby the snow will be removed in successive layers, beginning at the top, substantially as described.
